My situation is almost the same as yours. I'm a teen, not that heavy, higher cervix, and I'm planning on losing my virginity soon enough, so I shopped with that in mind.

I just bought a Sm Yuuki, 'cause it's a bit longer and a bit wider than most of the small sizes. It also has grip rings on the base of the cup which I thought would be helpful for me, since I'm a beginner.

I haven't been able to use it yet, though, 'cause it was only delivered about a week or two ago, and I haven't gotten my period yet =/

OK, good. You have a general idea of what will fit you -- but you're not sure of shape.

Check out Melissa's photos at http://menstrualcups.friendhood.net/moderator-s-photo-library-f52/ She has a zillion cups and her pictures show side by side comparisons. Maybe that will help you narrow your choices.

Not to sway you but I am drawn to the Shecup. At 44x54, it's fairly long, but despite the body shape, it seems fairly narrow. It has a little nub instead of a stem. Melissa doesn't have a category for it but it shows up in other cup comparison photos (link above.) And if you like it, compare prices at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190415014781 (appx US$25 with today's exchange rate) and elsewhere online.

Does the shape really make that much of a difference? I am just unsure if that will really make or break wearing the cup.

Some people feel the difference more than others. I think you're most likely to feel a difference if the cup is borderline too large or small.

If you're young and accustomed to inserting things for either function or pleasure, width won't really matter "that much." You can accommodate a folded size for insertion and removal, and your vaginal muscles are toned enough to hold either a narrow or wide bodied cup in place.

Once you get older and/or have a bunch of kids, the cup's body width starts to make more and more of a difference.

So no, I doubt it will make that much of a difference to you.

You already have a general idea of what might fit you. Choose the one that "calls to you." I don't know if it's intuition or self-fulfilling prophesy, but that gut feeling is usually right.

Ohh ok. Well I just ordered the size 1 diva cup so hopefully that works. I'll keep you guys posted, and I'm so glad I have all this useful info from you guys :)

Have you checked the height of your cervix during your period? A lot of folks find it drops substantially lower during menstruation, so it's important to find its lowest descent in determining if you need a short cup.

Personally, I'm a fan of the short cups with long stems, so you can have plenty to grasp onto for removal when you're learning, but you can also trim it down substantially if it feels too long. You probably don't want the tiniest cup if the width doesn't scare you because you'd more likely to "outgrow" it; a "middle of the road" sized cup will probably last you longer. Good luck!
